# std::fputc, std::putc

From cppreference.com
< cpp‎ | io‎ | c

Defined in header `<cstdio>` |  |
int fputc( int ch, std::FILE* stream ); int putc( int ch, std::FILE* stream ); |  |

Writes a character ch to the given output stream stream.

Internally, the character is converted to unsigned char just before being written.

In C, putc() may be implemented as a macro, which is disallowed in C++. Therefore, calls to std::fputc() and std::putc() always have the same effect.

### Parameters

ch | - | character to be written
stream | - | output stream

### Return value

On success, returns the written character.

On failure, returns EOF and sets the error indicator (see std::ferror()) on stream.

### Example

Run this code

    #include <cstdio>

    int main()
    {
        for (char c = 'a'; c != 'z'; c++)
            std::putc(c, stdout);

        // putchar's return value is not equal to the argument
        int r = 0x102A;
        std::printf("\nr = 0x%x\n", r);

        r = std::putchar(r);
        std::printf("\nr = 0x%x\n", r);
    }

Possible output:

    abcdefghijklmnopqrstuvwxy
    r = 0x102A
    *
    r = 0x2A
